To all whom dit concern: 'Be it known that I, OSCAR Lisons,V a citi Y zen ofthe Republic'of SWitzerland,-.residing' in Chicago, in the county of Cook fand State 5 of Illinoisiave invented a new and useful Improvem j :t in zonizers, of which the following is ,aspecification. invention relates to machines for the cingof ozone for the purification and ringof airin dwelling houses and busi- Stablishments, 4by discharge of an, elec; urgent of high voltage: And the inmacchinari" this type, that shall have maximuni eliciency of action and simplicity of ect current through 2*,and to deliver an hrough the connections alternating c1`1rrent,t .13, 14, toV thevftra s i Same ilmerto manlainin high speed rotation lthe horizontal?motor-fan-shaft ,16.

former.. 4Surroundin this constantly rotating fan-electrode, an supported free thereof, is the cylindric glass annulus'26, constitiltingk a' cylindric annular dielectric completely surrounding, and in close and' uniform radial proximity to, the path of the peripheral edges of'the vanes of the said:

fan-electrode, and extending a considerable distance forward and to the rear of the zone of said path. Completel in immediate contact Wit this the' outer face of glass annulus, is vthe continuous stripor' surrounding and., ,Y 8 0 rin of metallic foil 27, ofconsiderablyfles's' v wi tlrthanthe Vglass annulus and forming vaA t continuous electrode Iuniformly opposed t0 and covering the zone of the path of the peripheral `edges of the vanes of the fanelectrode.- vThis metallic-foil electrode Lis,

connected, by the connection v28, With the otherpole of the transformer, and its outer surface and edges are completely covered by lthe strip of insulating tape 29 Whose over' lapping lateral edges are closely applied to ythe outer face of the glass annulus at-eitherside o f the foil strip and 'continuously laround the circumference thereof. The fiber strip 30, having its oppositel ends se- 'curedI to the base-plate of the machine, is passed over the top of the glass annulus, outside the aforesaid insulating tape, and presses rmly down, and steadies in position, the said annulus. 1

The transformer steps up the alternating current, received.,vfrorn-y the motor-generator,

and this high-voltage current is continuously discharged across the space between the inner face ofI the metal-foil electrode and of some thousands of'volts,

vthe. peripheral edges ofthe revolving vanas;-

of the fan-electrode, the 'discharge passing through the interposed dielectric annulus and jumping the air-spac'lietiveen the inner face of said annulus and the said peripheral edges of therevoltving vanes, the glass annu lus bengf"thin/enough,` and of such uni formity` and character, as to permit such continuous discharge to pass through it, at the same time preventing all sparkinv. The electric discharge is thus uniform and continuous and requires no interruption. The ozone is generated in the air that is sucled in from the rear of the fan and driven out into the said air-space across which said continuous discharge is taking place= between the peripheral edges of the revolving vanes and the opposed inner face of the glass annulus; and as fast 'as the ozone is L generated in said air-space, the fan action carries such ozonized air forward out of the range of said electric discharge, thus maintaining a constant How of cool air and preventing the overheating that would develop noxious gases and deteriorate the ozone if the latter were permitted'to dwell in said continuous electric discharge.v rlhe oaoriizedl air4 driven forward by the fanelectrode impinges against the inclined re- Hector-plate 3l that is secured Within the casin 1n frontof the fan, and is thence rc lecte upward and driven out through the horizontal fine-meshed screenlate 32 that covers the entire above-desem ed mechan ism Within the easing. The top chamber 33 35 of the easing, above said horizontal screenplate 32, is provided on all four sides With the vertical strips of coarser-meshed screenplate 34:, through which the aforesaid ozonized air flows out into the surrounding room. The inverted conical d'etlector 35, se cured` to the under side .of the top of the casing and positioned substantially above the front of the fan, facilitates the deflection and distribution of the ozonized air toward the said several sidescreens of the upper chamber of the casing. The air to be ozonized may be sucked into the casing through the, screened aperturing 36 in the rear casing-Wall. A several-point switch 37, and resistances 38, 39, 40, are-interposed in the connections through which the direct current passes to the motor-generator, so that several dlierent controlled speeds may be obtained.

In prac cal operation this mechanism maintains a constant large outtiow of air highly charged with ozone of the greatest possible purity, practically free of any incasurable trace of noxious ases. ihe air-flow maintained by the faire ectrode acts to automatically keep the discharging edges of the vanes and the opposed face of the glass annulus free of dust that would otherwise ac cumulate and interrupt the continuity of the electric discharge.

The positioning of the entire mechanism. `in the lower chamber of the casing, below the horizontal screen-plate and the laterally screeiledyin upper chamber, precludes the possibility of the user meddling With the 'mechanism or suffering a dangerous shock by thrusting any metallic instrument into contact With the high-voltage contacts; and this is a consideration of some importance because such danger has not been adequately guarded against in other machines of this character that have been devised for com# mercial use.
